Overview of variable valve timing technology

- Sep 03, 2018 -

In recent decades, in order to improve the automobile engine power, economy and reduce sewage requirements, many countries and engine manufacturers, scientific research institutions put a lot of manpower, material resources for the research and development of new technologies.

At present, these new technologies and methods, some have been applied in the internal combustion engine, some are in the development and improvement stage, it is possible to become the future development direction of internal combustion engine technology. Engine variable Valve Timing technology (VVT, Variable valve Timing) is one of the new technologies that have been used in modern cars in recent years, and the engine adopts variable valve timing technology to increase the intake charge, increase the charge factor, and the torque and power of the engine can be further improved.
